HUMIDIFIER.

Specification of Letters Patent.

Application filed April 22, 1909.

Patented May 17, 1910.

Serial No. 491,432.

To all whom it may concern:

Be it known that I, ROBERT P. SMITH, of WVinchester, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Humidifiers, of which the following is a specification,reference being had to the accompanying drawings, forming part thereof.

This invention has reference to improvements in humidifiers and relatesparticularly to improvements in humidifier casings.

The object of the invention is to so con struct a humidifier casing thata part or section thereof may be swung outward and upward in a peculiarmanner.

The invention consists in the peculiar construction of the humidifiercasing comprising segmental sections and in the peculiar manner ofpivoting one of said sections.

Figure 1, represents a front elevation of parts of a humidifier casingshowing the peculiar manner of mounting the movable section. Fig. 2,represents a similar view of portions of the casing sections showing theposition of the swinging section when opened. Fig. 3 represents a viewof portions of the machine, partially in section, showing theconstruction of the upper hinge. Fig. i represents a similar view of thelower hinge.

Similar numbers of reference designate corresponding parts throughout.

As shown in the drawings in its preferred form 5 represents the hangerhaving the depending arms 66 to the lower ends of which is secured thedrip pan 7 which carries the spacing members 88.

Secured to the depending arms 66 of the hanger 5 is the main casingsection 9, segmental in shape, and having at its lower end the segmentalflaring rim 10 secured to the drip pan 7 by bolts 11-11. One edgeportion of the segmental opening of this casing section 9 has the button12 and the corresponding edge portion of said section has, at its upperend, the socket 13, while the lower portion of rim 10 has the socket 14.

The swinging casing section 15, is preferably segmental in shape, to fitbetween the edges of section 9, and has at its upper portion the member16 furnished with one end journaled in the socket 18, while at its lowerend, this section 15 has the flaring rim 17, adapted when closed to fitbetween the ends of rim 10, which is furnished with the member 18 havingan end j ournaled in the socket 14. On said section 15 is mounted thelatch 19 adapted to engage the button 12 when said section 15 is closed.

Under some conditions of use the currents of air, induced in thehumidifier casing by the moistening spray, carry to the moistenedinterior of the machine lint, fluff and other foreign matter which, attimes, it is desirable to remove and in such event the casing member 15may be released from its holding device and swung outward on its pivots,which in efiect are ball and socket joints, so that the free edge of therim 17 may swing upward, as well as outward, until it is swung past thesocket 14: after which section 15 swings toward the main casing section9 which forms a stop for the hinged section 15, the overbalancing ofsaid hinged section thus preventing the accidental closing of saidhinged section. When the swinging section is thus opened access may behad both to the interior of casing section 9 and to the rim 10, as wellas to the parts contained within said section 9 and its rim. After whichthe section 15 may be closed. In the open position the inclination ofthe rim 1'? tends to direct the flow of any moisture accumulated thereontoward its lower pivoted portion whence said moisture may flow into thedrip pan 7.

Having thus described my invention I claim as new and desire to secureby Letters Patent.

1. A humidifier comprising a casing formed of segmental sections ofwhich one has a flaring rim, a ball and socket joint connecting theupper part of said section and an adjacent fixed part of the machine,and a ball and socket joint connecting the lower end portion of saidflaring rim with a corresponding fixed part of the machine.

2. In a humidifier the combination with a segmental casing sectionhaving a flaring ings being mounted on the flaring rim of rim at itslower end, and socket; mounted said movable section. res ect-ively atthe upper art 0 said sec- H01? and at the outer edge df said rim, of aROBERT SMITH 5 second segmental casing member having a Witnesses:
